A green-focused home improvement retailer called TreeHouse was born last month when the founders opened a 25,000-sq.-ft. store in Austin, Texas.

The business owners said they recognized the growing demand for sustainable and healthy-living products, which are organized across the store in the categories of health, performance, corporate responsibility and sustainability.

One theme of the store: Being green doesn't always mean you have to pay more or change your lifestyle.
